Air Calédonie flies to the Isle of Pines from Nouméa between several times a day. Japanese day-trippers often pack the planes, so book well ahead.
The isle's wartime airport sits on an 81-meter-high plateau at the center of the island, nine km from Kanuméra. All of the gîtes provide paid airport transfers for those who have reserved a room.
The interisland ferry Betico ties up to the wharf on Kuto Bay. The 2.5-hour ferry ride from Nouméa usually occurs on Wednesday, Saturday, and Sunday at 0700, departing Kuto for the return trip at 1700, which allows seven hours on the island if you want to make a day trip of it. A bus that meets the ferry offers a day trip to Oro Bay.
The gîtes can arrange car rentals. The Shell service station between Kuto and Kanuméra rents scooters but they're often all taken, so reserve the day before.
Traffic is thin around the island, but most people will give you a lift, and if you don't mind doing some walking, you should be able to complete the 40-km loop around the island in one day.
